FIG. 1 is a front, right side perspective view of a steam hair straightener showing my new design;

FIG. 2 is a top plan view of the steam hair straightener of FIG. 1;

FIG. 3 is a right side elevational view of the steam hair straightener of FIG. 1, the left side elevational view being a mirror image thereof;

FIG. 4 is a front elevational view of the steam hair straightener of FIG. 1;

FIG. 5 is a rear elevational view of the steam hair straightener of FIG. 1; and,
